A Comparative Study on the Effect of Cemented and other Different Biological Type of Artificial Femoral Head Prosthesis in the Treatment of Intertrochanteric Fractures in the Elderly
By Li J, Jia F, Xiao J et al.
Abstract Background: The aim of this study is to assess comparatively the clinical effect of cemented and other biological type of artificial femoral head in the treatment of intertrochanteric fractures of the femur in elder patients.Methods: The clinical data of 121 patients with unstable intertrochanteric fractures treated with hip replacement from July 2017 to December 2018 in our hospital were reviewed.Results: There were 121 patients with unstable intertrochanteric fracture received hip replacement enrolled in this study. Of those patients, 60 patients received bone cement femoral prosthesis (bone cement group), while 61 cases (62 hips) received biological femoral prosthesis (biological group). The results showed that the biological group treated had shorter operation time, less intraoperative bleeding and longer time of complete weight-bearing than the bone cement group (P < 0.05), but there was no significant difference in the time of partial weight-bearing and Harris score of hip joint function between the two groups (P > 0.05). Conclusion: The cemented and biological artificial type of femoral head might lead to satisfactory short-term results in the treatment of intertrochanteric fractures for elder patients. Results showed that the biological group had shorter operation time, less intraoperative bleeding and longer time of complete weight-bearing than the bone cement group. For the unstable intertrochanteric fracture of femur with severe osteoporosis and difficult to maintain stability after fracture reset, biological femoral prosthesis stems might be employed for the treatment of artificial hip replacement according to the shape of the proximal femoral cavity, the quality of bone and the range of fracture coverage, which may promote the recovery of hip joint function and obtain good clinical effect.
